I am trying to record a lecture using Photo Booth on my Macbook but I want to be able to record what the professor has on the board. Unfortunately, photobooth seems to have a mirror image, so that all the writing is reversed. How do I get the camera to be a normal non-mirror camera?
In the menu bar click Edit, then "Auto Flip New Items". After you do that, the photos and videos you take will capture what the camera sees, and not reverse it.
Record using QuickTime.
I was having same problem and rather than change PhotoBooth to flip all images, I use one app to record people making fun faces and another for lectures.
I had exactly this problem for a presentation, so wrote a app called QCamera which supports both mirrored and normal capture. You can download it for free from the Mac App Store.
